PHILADLEPHIA (RNN) – Police will arrest a man who was operating a piece of heavy equipment when a building collapsed on a Salvation Army Thrift Store killing six people and injuring 13.
Sean Benschop, who was operating an excavator when the building collapsed, tested positive for marijuana and prescription pain medication, according to multiple media outlets in Philadelphia.
The 42-year-old man will be charged with six counts of involuntary manslaughter as well as charges of risking and causing a catastrophe, according to The Philadelphia Inquirer.
Benschop, who has reportedly faced drug charges in the past, was treated at the Hospital of the University of Pennsylvania where blood was drawn. He was released from the hospital with minor injuries.
Police are searching for Benschop, and have raided his home, but have not located him, according to the Associated Press.
The AP also reports Benschop also goes by the alias Kary Roberts and has been arrested more than 10 times since 1994 on a variety of charges including drugs, theft and weapons possession.
A lawsuit has been filed against demolition contractor Griffin Campbell, Benschop's employer and the company that was hired to take down the building.
On Friday, Mayor Michael Nutter announced new building demolition regulations at a news conference.
"Our goal here is to increase public safety at these private demolition sites, to bring them up to the same high standards that we maintain on public demolition sites," Nutter said.
